Answer:
warmer
Explanation:
The law of conservation of energy tells us that energy cannot be created or destroyed, it can be transferred or converted from one from to another. In this question when the beer that is at room temperature is put in the fridge, it loses some heat energy. This heat energy is not destroyed, the fridge through multiple processes eventually releases this heat to the room through pipes at the back which is why they are normally warm. the heat from the food inside is expelled to the room. It is not lost.
That's true.
And I'll go ya a better one:
If the object is moving or not moving, at a constant or changing speed, in a straight or curvy line, and the forces on it do not cancel out and add up to zero, the object will accelerate.
Answer:
Explanation:
Given
density of cylinder is 
Length of first cylinder is 
radius 
For cylinder 2 
and 
are the height above water
E
as object is floating so its weight must be balanced with buoyant force
For 2nd cylinder
Dividing 1 and 2 we get
Yes they should all be going the same speed.
Hope this helped :)
